Strong Amphiphobic Porous Films with Oily-self-cleaning Property beyond Nature

Abstract

Abstract The lotus leaf is known as one of the natural self-cleaning plants, which can easily roll off water but not oil droplets. Herein, a simple chemical bath deposition method to fabricate superhydrophobic and strong oleophobic surfaces was presented on porous substrates such as fabrics and nickel foams. The resultant substrates exhibited excellent superhydrophobicity and good oil repellency. More significantly, such surfaces possessed self-cleaning property for water, as well as to oils such as glycerol and rapeseed oil.
